We're dividing 122015 by 99 
The aim is to understand the frequency of 99 in 122015.

Going ahead to step 1:
99 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 99

Going ahead to step 2:
When dividing 12 by 99, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 99

Going ahead to step 3:
When dividing 122 by 99, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 99 away from 122, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 99

Going ahead to step 4:
99 goes into 230 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 198 from 230 and we're left with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 99

Step 5:
If we divide 321 by 99, we get 3 and a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 297 from 321 and we're left with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 99

Moving on to step 6:
245 divided by 99 is 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 1232.0
If we take 198 away from 245, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
99 goes into 470 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 1232.4
Subtracting 396 from 470 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
The number 99 fits into 740 7 times, leaving a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 1232.47
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
If we divide 470 by 99, we get 4 and a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 1232.474
Deduct 396 from 470 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
If we divide 740 by 99, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 1232.4747
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
470 divided by 99 is 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 1232.47474
Subtract 396 from 470 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
99 can be fit into 740 7 times, resulting in a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 1232.474747
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
470 divided by 99 is 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 1232.4747474
Deduct 396 from 470 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
If we divide 740 by 99, we get 7 and a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 1232.47474747
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 1232.47474747 with a remainder of 4.7e-08.
